  • Triangular silver nanoplates as a spectrophotometric reagent for the
           determination of mercury(II)
    • Authors: A. A. Furletov; V. V. Apyari; A. V. Garshev; S. G. Dmitrienko; Yu. A. Zolotov
      Pages: 1203 - 1207
      Abstract: The applicability of triangular silver nanoplates (TNPs) as a spectrophotometric reagent for the determination of mercury(II) in an aqueous solution was estimated. The method is based on the oxidation of TNPs with a mean edge length of 52 nm and thickness of 4 nm by mercury(II) ions, which is accompanied by a decrease in the surface plasmon resonance of nanoparticles. The effect of reaction time, pH of solution, and TNP concentration on the sensitivity of mercury(II) determination was studied. The limit of mercury(II) detection under the selected conditions was 0.022 μg/mL.

  • Determination of copper in urine by diffuse reflectance spectroscopy
    • Authors: V. P. Dedkova; O. P. Shvoeva; A. A. Grechnikov
      Pages: 1208 - 1211
      Abstract: A possibility of determining copper(II) after adsorption on polyacrylonitrile fiber filled with a KU-2 cation exchanger with immobilized 1-(2-pyridylazo)-2-naphthol (PANF–KU-2–PAN) is studied. The diffuse reflectance spectra of the carrier discs before and after the adsorption of copper in the batch mode are recorded. The dependences of the analytical signals of the copper complex on PANF–KU-2–PAN on adsorption conditions are studied. The conditions for determining 0.05–0.40 μg/mL of copper(II) by measuring diffuse reflection coefficient at 640 nm or visually by a color scale after the adsorption of copper from 20 mL of a solution containing 0.01 M of HCl are found. The determination of 0.1 μg/mL of copper does not interfered with equal amounts of Co, Zn, and Pb and double amounts of Ag, Fe(III), Cd, Mn(II), Bi(III), and Cr(III). The procedure is used for urine analysis. The following conditions of the preparation of urine samples for the determination of copper were selected: boiling with hydrogen peroxide followed by acidification to pH 2. A procedure for determining copper in urine with a limit of detection of 0.03 μg/mL was developed; the relative standard deviation does not exceed 25%; the duration of analysis of 5–6 samples is 30–35 min.

  • Spectrophotometric determination of proteins in biological fluids
    • Authors: P. V. Anisimovich; T. B. Pochinok; E. V. Tokareva
      Pages: 1212 - 1218
      Abstract: A comparative analysis of procedures of the spectrophotometric determination of total protein with various organic dyes, Bromocresol Green, Bromophenol Blue, and Pyrogallol Red, in biological fluids is presented. It is shown that the results of determination with various dyes can differ because of the specific features of reagent interaction with the components of biological fluids. A new organic reagent, Bromopyrogallol Red, possessing equal sensitivity to different protein fractions (albumins and globulins) and ensuring a minimum error of the determination of total protein in clinical examinations using calibration solutions of various compositions is proposed. A procedure for the determination of total protein in biological fluids is developed and tested on real samples of urine and blood serum.

    • Authors: M. V. Shashkov; E. E. Sergeev
      Pages: 1219 - 1225
      Abstract: Presumable structures of polyethanolamines, synthesized by the catalytic β-hydroxyethylation of ammonia with an excess of ethylene oxide are determined by gas chromatography–electron ionization mass spectrometry and tandem mass spectrometry qualitatively, following fragmentation ways and also taking into account retention data. The preferable paths of consecutive reactions of the synthesis of polyethanolamines in a homologous series of isomers are found.

  • Adsorption and selective properties of
           4-{4-[4(S)-2-methyl-1-butoxybenzoyloxy]phenyldiazenyl}benzaldehyde in
           gas–mesophase chromatography
    • Authors: S. A. Kuvshinova; G. V. Kuvshinov; O. I. Koifman
      Pages: 1226 - 1232
      Abstract: Adsorption of 16 organic compounds from the gas phase by 4-{4-[4(S)-2-methyl-1-butoxybenzoyloxy]phenyldiazenyl}benzaldehyde was studied by gas chromatography. It was shown by means of differential scanning calorimetry that 4-{4-[4(S)-2-methyl-1-butoxybenzoyloxy]phenyldiazenyl]benzaldehyde is an enantiotropic polymorphic mesogen and forms smectic and nematic liquid crystal phases. Electron-donor isomers of methylpyridine and dimethylpyridine, isomers of weakly polar xylenes and cresols, and enantiomers of 2,3-butanediol and terpene hydrocarbons, capable of various types of intermolecular interactions with mesogenic aldehyde, were selected as adsorbates. Specific retention volumes of adsorbates and criteria for their separation were calculated. The effect of temperature and chemical nature of the adsorbates on their adsorption redistribution in the gas–liquid crystal system is discussed. It was found experimentally that the adsorbent based on 4-{4-[4(S)-2-methyl-1-butoxybenzoyloxy]phenyldiazeny}lbenzaldehyde exhibits high selectivity for close-boiling organic compounds of various nature and good efficiency and productivity in their separation.

  • Chromatographic behavior of anthocyanins on a C10CN stationary phase
    • Authors: V. I. Deineka; Ya. Yu. Kul’chenko; L. A. Deineka
      Pages: 1233 - 1238
      Abstract: The selectivity of the separation of some anthocyanins on Diasphere-11-C10CN stationary phase (phase I) is compared with the traditional reversed Symmetry C18 phase (phase II). It is found that, in contrast to phase II, phase I is effective in the separation of isomeric pairs of anthocyanins of 6-hydroxycyanidin-3-rutinoside and delphinidin-3-rutinoside, 6-hydroxypelargonidin-3-rutinoside and cyanidin-3-rutinoside, which ensures the determination of anthocyanins of Alstroemeria flowers. A comparison of separation maps shows that, on phase I, as compared with phase II, retention does not decrease so much, when OH groups are added to the anthocyanidin structure; trend lines for 3-mono-, di-, and triglucosides have a higher slope, and the addition of a glucosidic substituent at position 5 results in a more significant decrease in the retention of anthocyanins. Different selectivity of the separation of anthocyanins on phase I makes this separation version a good alternative to traditional reversed phase chromatography.

  • Determination of alkyl- and alkanolamines in drinking and natural waters
           by capillary electrophoresis with isotachophoretic on-line
    • Authors: Yu. Malinina; M. Ya. Kamentsev; L. N. Moskvin; N. M. Yakimova; I. D. Kuchumova
      Pages: 1239 - 1242
      Abstract: A procedure is developed for the determination of several amines in drinking and natural waters by capillary electrophoresis with isotachophoretic on-line preconcentration without sample preparation. A background electrolyte based on acridine as an absorbing ion is proposed for analysis with isotachophoretic on-line preconcentration and indirect photometric detection. The sample was injected in the hydrodynamic mode. The procedure was tested on drinking and natural water samples. The accuracy of data obtained was confirmed by the added–found method. The analytical range was from 0.25 to 5 mg/L. The time of one analysis was 5–6 min.

  • Determination of sulfur-containing anions in alkaline solutions using
           arrays of DP-sensors based on hybrid perfluorinated membranes with
           proton-donor dopants
    • Authors: A. V. Parshina; T. S. Denisova; E. Yu. Safronova; Yu. A. Karavanova; D. V. Safronov; O. V. Bobreshova; A. B. Yaroslavtsev
      Pages: 1243 - 1250
      Abstract: The influence of proton-donor properties and concentration of dopant nanoparticles introduced into Nafion and MF-4SС perfluorosulfonic cation-exchange membranes on the characteristics of cross-sensitive DP-sensors (sensors whose analytical signal is the Donnan potential) in alkaline solutions of sulfur-containing organic compounds were studied. The dopants were acid salts of heteropoly acids (HPAs) and hydrated silica SiO2 and zirconia ZrO2 surface-modified with sulfur-containing groups and an acid HPA salt. A correlation was revealed between the DP-sensor sensitivity to anions (and zwitter-ions) in alkaline solutions, size and proton-donor ability of the added particles, and diffusion permeability of hybrid membranes. Optimum compositions of membranes for arrays of cross-sensitive DP-sensors ensuring the simultaneous determination of cations and anions (and zwitter-ions) in the test solutions with an error of less than 18% were selected.

  • Identification of endogenous and anthropogenic hydrocarbons in bottom
           deposits of peat lakes and evaluation of their contribution to the
           “hydrocarbon index”
    • Authors: E. S. Brodskii; A. A. Shelepchikov; E. Ya. Mir-Kadyrova; G. A. Kalinkevich
      Pages: 1255 - 1262
      Abstract: Gas chromatography with mass spectrometric detection was used to analyze bitumens isolated from bottom sediments of peat lakes contaminated with petroleum products. Endogenous hydrocarbons are characterized by the presence of n-alkanes with an odd number of carbon atoms in the molecule in the characteristic region of C23–C33, the absence of a “hump” characteristic of oil products in the chromatogram, and the presence of light hydrocarbons, eluting in the initial part of the chromatogram (light hydrocarbons are usually lost when the sample is dried). The distribution profile of odd n-alkanes is used to assess the contribution of endogenous hydrocarbons to the “hydrocarbon index” with the help of the pattern recognition method. The concentration of light hydrocarbons is from 50 and 300–400 to 3500–5000 mg/kg for a number of samples and even up to 26000 mg/kg in some samples. The concentration of petroleum hydrocarbons and heteroatomic compounds varies from the lowest values of 30–80 mg/kg up to 20000 mg/kg and higher.

  • A rapid field test method for the determination of hydrogen sulfide and
           sulfides in waters with gas preextraction
    • Authors: M. O. Gorbunova; E. M. Bayan
      Pages: 1263 - 1269
      Abstract: A rapid test method was developed for the determination of hydrogen sulfide and sulfides in waters using a potassium chloride-impregnated test paper with color intensity evaluation of the formed CdS zone by colorimetry and diffuse reflectance spectroscopy. The determination conditions, viz. acidity, gas preexraction time, air pumping rate, and working concentration range (0.005–0.16 mg of Н2S/L), were optimized. The procedure proposed is easy-to-perform, and the time of single determination is 20 min; in addition, the procedure is cost effective, sensitive, selective, does not require expensive equipment and expertise of executor, and is not inferior in accuracy to photometric methods. The procedure was tested on real water samples. The concentration hydrogen sulfide in the Don and Temernik rivers in Rostov-on-Don is not higher than the maximum permissible concentration (MPC).

    • Authors: V. M. Gruznov; M. N. Baldin; M. V. Pryamov; E. M. Maksimov
      Pages: 1155 - 1160
      Abstract: A procedure is proposed for the determination of the vapor concentration of 2,4,6-trinitrotoluene (TNT) in air at a level of 10–16 g/cm3 in the control of objects for the presence of TNT. The procedure includes preconcentration of TNT vapors and gas chromatographic determination with a limit of TNT detection at a level of 0.08 ± 0.02 pg in a sample. The procedure was applied to the control objects in cells of typical automatic luggage locker with sampling through sampling air ducts. A measure of sample losses as the breakthrough of vapors through sampling air ducts and gas dynamic conditions for the reduction of vapor losses as the ratio of diffusion coefficient to the air duct flow rate were proposed. The time constant of the saturation of the sampling system with TNT vapors and the time constant of its cleaning were determined. It was shown that TNT vapors can be detected virtually satisfactorily near TNT-containing objects with sampling through long channels.

  • Adsorption–photometric determination of lead in cattle liver
    • Authors: R. A. Alieva; U. M. Abilova; N. S. Guseinova; F. M. Chyragov
      Pages: 1161 - 1166
      Abstract: A styrene–maleic anhydride copolymer is synthesized, modified in the presence of p-sulfoaniline and formaldehyde, and a new polymer adsorbent is obtained and identified by IR spectroscopy. The ionization constants of ionogenic groups in the adsorbent are determined by the potentiometric method. The adsorption and desorption of lead(II) on the obtained adsorbent are investigated, and optimal conditions of preconcentration are determined. An adsorption–photometric procedure for the determination of lead is proposed, including the adsorption preconcentration of lead(II) from a buffer solution with pH 6 and desorption with a solution of HCl (with the desorption rate of up to 99%). The procedure was used to determine lead in the cattle liver.

  • Sorption, thermodynamic, and selective properties of camphor-substituted
           copper(II) tetrapyrazinoporphyrazine as a stationary phase for gas
    • Authors: G. V. Kuvshinov; S. A. Kuvshinova; O. I. Koifman
      Pages: 1172 - 1177
      Abstract: The surface of a Chromaton N-AW diatomite adsorbent was modified with copper(II) tetra(1',7',7'-trimethylbicyclo[2.2.1]heptano-[2',3'-b]-pyrazino)porphyrazine. Adsorption of vapors of 20 organic compounds on the surface of the modified adsorbent was studied by inverse gas chromatography. Electron-donor isomers of methylpyridine and dimethylpyridine, isomers of weakly polar xylenes and cresols, aliphatic alcohols, and other hydrocarbons capable of showing various types of intermolecular interactions with the complex of camphor-substituted tetrapyrazinoporphyrazine with copper(II) were chosen as adsorbates. Specific retention volumes of adsorbates, heat and adsorption entropy, and Gibbs adsorption energy were calculated. The effects of temperature and chemical nature of the adsorbates on the thermodynamic characteristics of sorption are discussed. Factors of separation of closely-boiling hydrocarbons are calculated. It has been found experimentally that the macroheterocycle-based adsorbent shows high selectivity to closely-boiling compounds of various types, unattainable for the unmodified adsorbent.

      Abstract: Preparative isolation of aromatic metabolites from lichens of the Cladonia genus (C. stellaris, C. arbuscula, C. amaurocraea, and C. rangiferina) growing in Central Yakutia was carried out. Identification by IR, UV, and time-of-flight mass spectrometry has shown that the isolated compounds belong to the group of lichen substances. It was shown that the component composition of the studied lichens corresponds to the previously described one. At the same time, the concentration of perlatolic and barbatic acids in C. stellaris and C. amaurocrae lichens, respectively, growing in Central Yakutia found by HPLC is higher than in similar types of temperate climatic zones.

      Abstract: The appearance of a new APINAC compound (AKB-57, ACBL(N)-018, adamantan-1-yl-1-pentyl-1H-indazol-3-carboxylate) in the Russian market of psychoactive drugs led to the need in setting measures of state control over its turnover and in solving the problem of categorizing this compound as a potentially hazardous psychoactive substance. To establish these control measures, it was necessary to determine the appropriate chromatographic–mass spectrometric characteristics and to search for its metabolites for their subsequent automated detection. The structure of an APINAC molecule has significant similarity with the molecules of other synthetic cannabinoids. In this paper, primary information on the metabolism of APINAC in the body of rats is presented. A number of putative metabolites, which are the products of hydrolysis of the initial structure and additional monohydroxylation of these products, carbonylation and carboxylation of the lateral N-pentyl chain of indazole-containing metabolites, were detected in rat urine by liquid chromatography–mass spectrometry in the mode of measurement of exact masses and gas chromatography–mass spectrometry. It was found that the formation of glucuronides is characteristic for 1-adamantol and its monohydroxylated metabolite and for the indazole-containing product of hydrolysis of APINAC. The presented mass spectra and retention characteristics of the detected metabolites can help in the detection of these (or similar) compounds in human urine.
